Deep Intelligence Across Industries

SUMCO is the world's second-largest maker of silicon wafers for semiconductors and the purest listed play on the wafer cycle. All of its revenue comes from one reportable segment, high-purity silicon. It grows single-crystal silicon ingots by the Czochralski method and turns them into 300mm and 200mm-and-below polished, annealed and epitaxial wafers for memory, logic and power-device makers. Its fused-silica crucibles come from its own JSQ Division, and since 2023 its polysilicon has come from Kojundo Silicon. That makes it unusually vertically integrated across the three critical inputs of crystal growth. FY2025 revenue was ¥409.7 billion, with 80.6% earned outside Japan and 37% in Taiwan. The company describes its global share as roughly 30%. AI-driven demand for leading-edge logic, HBM/DRAM and server NAND pushed 300mm shipments to a record of more than 8 million wafers a month in Q2 2026. However, depreciation from its 2023–2025 greenfield build-out has kept the company loss-making for five straight quarters. Management has now switched from adding capacity to upgrading existing lines and is waiting for wafer prices to recover before restarting greenfield construction. --- **What the company does.** SUMCO makes and sells high-purity monocrystalline silicon wafers, the substrate on which almost all integrated circuits are built. Production runs through a fully integrated chain: polysilicon feedstock (Kojundo Silicon, acquired from Mitsubishi Materials in March 2023) → high-purity quartz-glass crucibles (JSQ Division) → Czochralski crystal pulling of 300mm and smaller ingots → slicing, lapping/grinding, etching, double-side polishing, cleaning, heat treatment (annealing) and epitaxial deposition → metrology and shipment. Its 2025 securities report describes the business as a single segment, "high-purity silicon," covering 300mm wafers, 200mm-and-smaller wafers and polysilicon. **Company self-description (FY2025 securities report).** SUMCO presents itself as a specialist manufacturer of silicon wafers for semiconductor device makers worldwide. It runs a material-supply model using polycrystalline silicon as raw material, and it works with customers on joint development to win "first call" status for wafers used in next-generation devices. Its corporate vision speaks of being "the world's No. 1 company in technology," a company of "lively employees with a strong profit mindset," and a company "strong in overseas markets." **Business and revenue model.** Revenue is almost entirely product revenue from wafer sales. There is no material service, subscription or licensing revenue. **Long-term agreements (LTAs):** Most 300mm volume is sold under multi-year LTAs that set volumes and prices in advance, some running to 2028. In Q2 2026 management said LTA prices "continued to be respected." Spot sales are a small share of revenue. **Trading-company channel:** Much of the volume to device makers passes through Sumitomo Corporation, which accounted for 27.0% of FY2025 net sales as a sales intermediary. **Pricing:** Prices are set per wafer and depend on diameter, crystal specification, flatness/nanotopography, defect density and whether the wafer is polished, annealed or epitaxial. Contract prices are not publicly disclosed. **Value-chain position.** SUMCO sits upstream of every semiconductor fab. Its suppliers are crystal-growth and polishing equipment makers, high-purity quartz sand producers (globally concentrated in Spruce Pine, North Carolina), graphite and carbon parts makers, and electricity providers. Its customers are foundries, DRAM/NAND/HBM makers, logic IDMs and power/analog device makers. Because the JSQ Division makes its own crucibles and Kojundo Silicon supplies polysilicon, SUMCO controls more of its own input chain than most wafer peers. The remaining weak link is its dependence on high-purity quartz sand. **Customer types and end-markets.** **Leading-edge foundries and logic IDMs:** Products bought: 300mm epitaxial and polished wafers for ≤7nm/3nm/2nm logic; End-market demand driver: AI accelerators, CPUs, smartphones **DRAM and HBM makers:** Products bought: 300mm polished/annealed wafers; End-market demand driver: AI data-centre memory, HBM stacks, server DRAM **NAND makers:** Products bought: 300mm polished wafers; End-market demand driver: AI server SSDs, agentic-AI storage workloads **Power and analog device makers:** Products bought: 200mm and 150mm wafers, epitaxial wafers; End-market demand driver: Power MOSFETs, automotive, industrial **Image sensor and specialty device makers:** Products bought: 300mm and 200mm epitaxial wafers; End-market demand driver: Consumer, automotive cameras **Independent characterization.** SUMCO is a high-fixed-cost, high-operating-leverage commodity-specialty hybrid. At the leading edge (sub-3nm logic epi and HBM-grade polished wafers), qualification cycles of two to three years and customer co-development create real switching costs and pricing power. In 200mm and below, competition from Chinese suppliers backed by state policy is turning the product into a commodity. The investment case therefore hinges on three things: the mix shift to leading-edge 300mm; how fast the record ¥115.7 billion depreciation charge of FY2025 (with FY2026 the peak year) rolls off under declining-balance accounting; and whether wafer prices can rise enough to justify the next round of capacity.
